According to the Comment Privilege page, one of the reasons we should comment is "Request clarification from the author". So did I, two days ago, in my first question here. It's been two days since I commented, but they didn't answered me. Apparently, they didn't see it. I have two reasons for that:
I checked their profiles several times, and they logged in these two days (Last seen [time]).
I took a look at some questions around here, and I realize that people asked something in the comments, and the answerer didn't answer it. In other words, the same case as mine.
Honestly, I would not create this question. Because I thought "well, let's use the chat then", but I don't have enough reputation for that! Argh :(
I don't think the people who answered my question don't care about what I commented there at all, because I was quite coherent and what I was asking is useful to clarify some points that I have felt doubtful.
Thus, even though I said "... or they just don't want to ask them?", I believe the problem is that they aren't being notified. And I would like to join the chat. :(
I'm sorry if I was a little bit rude with my question. I'm new here and I thought that maybe they were not being notified.
